A volcano is a place where magma reaches the earths surface to become lava. Which comes out of an opening that is called a fissure.

What is the process where new oceanic lithosphere formed?
New oceanic crust is created at the mid-ocean ridges where rift volcanoes feed solidifying magma from the asthenosphere to both sides of the divergent plate boundaries. The mid-ocean ridge marks the line where heat from the Earth's interior is being carried to the surface by convection currents in the mantle. At the opposite end of the convection currents, colder, denser, and older oceanic crust is being drawn down into the asthenosphere, the birth to death of oceanic crust occurring in roughly 150 million year cycles.
What happens to an oceanic plate as it pushes against another plate?
When oceanic plates push against one another they cause subduction or adduction earthquakes. These plate tectonics take place on ocean floors all over the world.
What is a place where the crust of the lithosphere has fractured?
A place where the crust of the lithosphere has fractured is known as the asthenosphere. The asthenosphere is located below the lithosphere and is where plate tectonic movement occurs.
What occurs in the lithosphere?
The natural disaster that takes place in the lithosphere is Earthquake.
Places where new sea floor is being created?
New oceanic crust is formed when volcanic activity disrupts the seafloor at the mid- ocean ridge. When this occurs it is referred to as oceanic spreading.
What is jupiters geosphere like?
Mars' geosphere (or lithosphere) is dry, cold and arid. Like the Earth's lithosphere, the Martian lithosphere is the not-so-rigid part of the crust of Mars which is cooler than the interior of Mars somewhat like the foam on top of a cup of hot cocoa. On Earth, the lithosphere can be pushed in response to the warmth of the Earth. Warm magma rises to the very surface and pushes the cooler, rocky lithosphere aside. The lithosphere then subducts, melts, and becomes part of the warm rising magma again. Thus on Earth, the recycling of the lithosphere keeps the lithosphere from becoming too thick. Unlike the Earth, the rocky material which comprises the lithosphere of Mars does not contain enough trapped water to allow the rocky material to slide against each other. Since portions of the rocky material cannot slide against each other, the lithosphere cannot make way for hot, rising magma from the interior of Mars. Thus the lithosphere stays in place and thickens by cooling gradually. So it is that Mars does not have plates moving on the surface.

What kind of metamorphism might take place at a divergent boundary?
When a divergent boundary occurs beneath oceanic lithosphere, the rising convection current below lifts the lithosphere producing a mid-ocean ridge!!!Hope i helped.
Where is ocean floor created?
The ocean floor is made of relatively young basaltic rock which is pushed up as magma at the mid-oceanic ridges, the place where the sea floor spreads apart.

Why oceanic crust younger than the continental crust?
Oceanic crust is constantly created and recycled due to place tectonics. Oceanic crust is created by spreading ridges in the ocean floor and the oceanic plates subside under continental plates thus forcing it back down into the magma as the plate grows. Searching Oceanic Plate Tectonics on google will provide images that made this easier to understand.
What occurs in the lithosphere?
The natural disaster that takes place in the lithosphere is Earthquake.
When an oceanic plate collides with a continental plate is the oceanic plate forced down into the mantle?
An earthquake is made. Shock waves move in all directions from that place ( which is called the focus) and then it reaches the ground. This point is called the epicenter. The earth then starts violently shaking.
What is the difference between volcanism at a hotspot and volcanism at mid-ocean ridge?
At a hotspot, a plume of hot magma comes up through the mantle, causing vulcanism. At a mid-oceanic ridge, two plates move away from eachother, leaving space that is filled by magma. Hotspots and mid-oceanic ridges can exist together at the same place, Iceland being a prime example of this. However, Hawaii, which is also a hotspot place, is nowhere near plate boundaries, so it's not a place where you would normally expect vulcanism.
